Celestial Mote (H)

You place a mote on a creature of your choice that lasts for 8 hours, whenever you cause a creature to restore hit points (including yourself) the creature with the mote also regains hit points equal to your proficiency bonus as long as both targets are within 60ft of you.

This spell ends early if you cast this spell again, you are incapacitated or you are reduced to 0 hit points.
